[0026] It should be noted that, in the present embodiment, the sludge squeezing treatment machine 11 comprises a frame 111, a squeezing roller 112, a squeezing motor 113 and a conveying squeezing draining belt 114. When the solar energy reverse control integrated machine 126 starts the squeezing motor 113 to work, the squeezing motor 113 rotates and drives the squeezing roller 112 connected thereto to rotate. Since the two squeezing rollers 112 are connected by gear meshing, when the squeezing motor 113 rotates and drives the squeezing roller 112 connected thereto to rotate, the other squeezing roller 112 is driven to rotate through the gear meshing rotation. By being located at the conveying squeezing draining belt 114 and rotating simultaneously, the sludge on the conveying squeezing draining belt 114 is physically squeezed to remove excess water, thereby reducing the burden of subsequent drying treatment.

[0027] The solar panel 121 collects solar energy and converts it into electrical energy, which is connected to the solar inverter 126 through a wire.
